德兴铜矿岩体渐进破坏对边坡稳定性的影响

The Effect of the Progressive Failure of the Rock Mass on the Slope Stability in Dexing Copper Mine

德兴铜矿是我国特大型斑岩铜矿，采场边坡爆露时间长，岩体强度的动态变化对采场边坡稳定性有着很大的影响。为此，分析了水的侵蚀、硫化矿物的氧化特性及所引起的边坡渐进破坏规律，探讨了岩体渐进破坏对边坡稳定性的影响。

Dexing Copper Mine is an extra big porphyry copper mine in China and the mining slope are long exposed.As a result,the dynamic change of the rock mass has great effect on the slope stability.Therefore,the water erosion,the oxidation characteristics and the law of the slope progressive failure caused by them are analysed and the effect of the progressive failure of the rock mass on the slope stability is discussed.
